The handsome gabled mansion of unusual plan is centred on two octagons with a demi-octagonal porch. The 'lying-pane' (horizontal) window glazing must be one of the earliest examples of this Scottish fashion in the Highlands. The central octagonal parlour is flanked by dining and drawing rooms, all with ornate plaster ceilings.

Some of the building stone came from Cullicudden on the Black Isle, and was transported up the Dingwall canal and then by road to Coul; brick came from Brora, Sutherland, and slate from Easdale, Argyll.
